5.B.1 Configuration Support T
All Multiple Interactive Screen ports
e
must be assigned
in a sequential group. If a non-MIS device
G
is attached
to a MIS-configured port, the secondary logical-terminal
address
G
assigned to that port is reserved and may not
be addressed by the host. Recustomization is necessary to
free such addresses, and will cause all secondary addresses
to be redefined.
The number of secondary logical addresses
CD
must be in
ascending order. For example, the number of the secondary
address assigned to Port 3 must be equal to or greater than
the number of secondary addresses.
For 3274s operating in BSC, the maximum number of
logical addresses is 32
C).
For 3274s operating in SDLC,
the maximum number of logical addresses is 76.
If an addressing problem is suspected or if MIS devices
cannot be configured for multiple interactive screens, check
customization responses 1 12, 116, 117, and 118 (Config-
5-32
uration Support D) or 112, 170, and 171 (Configuration
Support T). If the problem still exists, refer to Chapter 2,
Step 5.
5. B.2 Configuration Support D
If the 3290 with interactive screen was previously
customized, running the /B test displays a table that shows
which physical ports have a primary and secondary address
associated with them. See Chapter 2, Figures 2-7 and 2-8.
Warning: When device cables are being exchanged and the
devices are different or the screen size or features are not
the same, addressing problems may occur which can affect
system operation.
It
is possible to have unassigned Type A ports
if
port
addresses were individually configured. Run the /3 test,
and check for x in line 2. See Step 5, item e, example C.
